Abstract
The invention relates to a cutter shell with a keep space on an installation end surface inside diameter. A center hole which is used for installing a cutter shaft is arranged in the center of the cutter shell, and the end surface of the cutter shell is an installation end surface which is in contact with the cutter shaft. The cutter shell is characterized in that the transition part of the installation end surface and the center hole is provided with a keep space for reducing the area of the installation end surface, and a step transition is formed between the installation end surface and the center hole. In the invention, the keep space is arranged on the inside diameter of the installation end surface of the cutter shell, namely, a step is arranged on the transition part of the center hole, thus, the area of the installation end surface is reduced, and the deformation of the installation end surface can be reduced even if the cutter shell is heated to expand; in addition, because the keep space provides a deformation space, the deformation of the installation end surface is further reduced, the deformation incline of the installation end surface is prevented, and the assembling precision is ensured.
Description
Technical field
The present invention relates to a kind of cutter shell of mounting cutter, specifically relate to a kind of cutter shell that the empty avoiding of end face internal diameter band is installed, belong to the Machining Technology field.
Background technology
In machining, cutter is necessary parts, so installing and fixing of cutter also is a very important structure.Cutter is installed on the cutter shell, and tail end inserts in the centre bore of cutter shell, fixedly mounts again.Installation end face on the cutter shell is the plane of an integral body, and the installation accuracy of stage property is that very strict requirement is arranged.Therefore very high to flatness and required precision that end face is installed.But, be integral planar because end face is installed, there is error will have influence on assembly precision slightly.Simultaneously, the cutter shell can expanded by heating, but the cutter shell install end face because face is bigger, expanding can be bigger, bulk expansion can be inhomogeneous, cutter shaft can cause plane deformation after installing, and has a strong impact on assembly precision, sometimes also can cause cutter shaft that the back run-off the straight is installed.
Summary of the invention
Be to solve the deficiencies in the prior art, the object of the present invention is to provide a kind ofly to be provided with the cutter shell of empty avoiding, provide the cutter shell that the expansion space of end face is installed, reduce deformation place, reduce deflection, improve assembly precision at the installation end face internal diameter of cutter shell.
For achieving the above object, the present invention is achieved by the following technical solutions:
A kind of cutter shell that the empty avoiding of end face internal diameter band is installed, be provided with the centre bore that is used to install cutter shaft at the center of described cutter shell, the end face of cutter shell is the installation end face that contacts with cutter shaft, it is characterized in that transition position at described installation end face and centre bore, be provided with the empty avoiding that reduces to install face area, install between end face and the centre bore and form step transition.
The invention has the beneficial effects as follows: the present invention is provided with empty avoiding in the inner radius of the installation end face of cutter shell, just step is set at transition position with centre bore, so just reduced to install the area of end face, even cutter shell expanded by heating, also can reduce to install the deflection of end face,, further reduce to install the deflection of end face simultaneously because empty avoiding provides deformation space, prevent that the installation end facial disfigurement from tilting, and guaranteed assembly precision.
Description of drawings
Fig. 1 is the structural representation of cutter shell of the prior art;
Fig. 2 is the structural representation of the cutter shell among the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done concrete introduction.
Fig. 2 is the structural representation of the cutter shell among the present invention.
As shown in the figure, 1 is the cutter shell among the figure, and 2 is centre bore, and 3 are empty avoiding.The centre of cutter shell 1 of the present invention is provided with centre bore 2, is used to install cutter shaft.For the area of the installation end face that reduces to contact with cutter shaft, in that being installed, the transition position of end face with centre bore 2 be provided with empty avoiding 3, just between installation end face and centre bore 2, form step transition.
After being provided with like this, just reduced to install the area of end face, when expanded by heating, can reduce to install the swell increment of end face, and the expansion position also reduced, deflection reduces, thereby has guaranteed to install the precision of end face.Simultaneously, empty avoiding 3 also provides the deformation space that end face is installed, and originally the installation end face of integral planar owing to there is not deformation space, behind the expanded by heating, can cause the moderate finite deformation that end face is installed, and has a strong impact on assembly precision.Deformation space has been arranged now,, also can offset, prevented to install the distortion of end face, improved the assembly precision of cutter shaft greatly in empty avoiding place even certain expansion takes place.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
